This present study is the first to quantify the transmission of avian influenza virus H5N1 within flocks during the 2004 epidemic in Thailand. It uses the flock-level mortality data to estimate the transmission-rate parameter ( beta ) and the basic reproduction number (R(0)). The point estimates of beta varied from 2.26/day (95% confidence interval [CI], 2.01-2.55) for a 1-day infectious period...
Postmortem examination of poultry from several backyard flocks in the south England revealed five chickens (Gallus gallus) one flock with lesions compatible fowl cyst mite (Laminosioptes cysticola). All affected birds were mature hens and had subcutaneous fascial, randomly scattered, 1–5 mm, calcareous nodules. Histological findings included a thin fibrous capsule, embedding glassy, pale basoph...
The present work was conducted to compare the occurrence of Escherichia coli possessing virulence and ESBL genes in backyard and farmed poultry. Three hundred and sixty samples from the poultry kept in backyard system and 120 samples from the farmed birds were collected from West Bengal, India. Among the E. coli isolates of backyard poultry (O2, O10, O25, O55, O60, O106, UT), none of them posse...
PoTTLTRYMEN realize that it is essential to control poultry lice, particularly in the case of chickens. These parasites are also a problem to those who raise turkeys, ducks, geese, guineas, and pigeons or grow wild birds, such as quail and grouse, in captivity. Losses due to poultry lice throughout the United States run high in the millions of dollars each year as the result of death, especiall...
A total of 300 dairy cow sera from 60 dairy herds from three provinces (Nakhon Pathom, Ratchaburi and Kanchanaburi) in western Thailand were collected and examined for antibodies against N. caninum infection by competitive enzyme-linked immunosorbent assay and an indirect fluorescent antibody technique. Of these, 10% were positive to N. caninum infection and the herd prevalence was 35% (21/60)....
Serological survey of avian influenza virus infection of backyard chickens in Bosnia and Herzegovina
BACKGROUND Chickens are animals that are sensitive to thermal stress, which may decrease their production level in terms that it affects feed intake and thus, decreasing body weight gain. The Heat Shock Factors (HSF) and Heat Shock Proteins (HSP) genes are involved in the key cellular defense mechanisms during exposure in hot environments. Aimed with this study to analyze the expression of HSF1...
